'lO ALL WHOM IT MAY CONOERN:

Be it knoivn that we, JOSEPH H. CRUMB und LEWIS SEARS, of De Ruyter, inthe county of Madison, and State of New Yorl l|ave invented a new anduseful Improvemcntin Cheese-Vat; and We do hereby declare that'thcfollowing isa full, clear, and enact description thereof, whichsv'illenable those skilled in the art to make and use the same,-iei`e1encebeing had to the accompanying drawings, forming` part of thisspecification, in which- I Figure 1 is atop view of the furnace andheaters.

Figure 2' is a cross-section of the same, taken in the line :c x in tig.l.

Figure 3 is a side elevation of one of the heaters. l

Similar letters of reference indicate corresponding parts in all thefigures.

This invention relates to neu' and useful improvement in cheese-vat,whereby an eicient and more durable apparatus is obtained. Heretot'oreheaters for cheese-mts have been constructed ot' sheet metal, but suchheaters are usually worn out in one o'r two seasons by rust and wear,and are necessarily made with plain surfaces, as so much, labor isrequired to put them together when corrugated that 'they become tooexpensive. lte construct our heaters oi' cast iron, and cest them withcorrugated fire surfaces so that their heating surfaces are largelyincreased, and, by the use ei' east iron, vessels ofmuch greaterendurance are obtained. We also employ a ileat for regulating the'supplyofwnter in the heaters, as hereinafter' explained.

In the accompanying drawings, A is the furnace, and a its chimney B Bare the heaters. The milk-vat C and its water jacket c are shown by redoutline in tig. 2. The heaters are connected together by pipes z', (iig.2,) and communicate with the Water-jacket c by a pipe, cl is the pipefor supplying cold Wat-er to the heaters, and is provided with a valveor cock, e, which is operated by a'iioat, f, so that when the water inthe heater falls the iioatf settles down and opens valve eend admitswater to the heaters until the oat'is elevated, and valve e closedagain, and by this arrangement the cold-Water feed for the heaters ismade self-acting. The sides of the vheaters B are corrugated, as shownby gs. l and 3, and their heating' surfaces thereby much increased. Bythese means the apparatus is made more elicient and more durable. A

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is

llhe employment of cast-iron heaters B, in combination with pipe b,hot-Water jacket c, and millmfat C, constructed substantially as and forthe purpose 'set forth. v

The floatfin connection with 'supply pipe and' valve d e, heaters B, andmilk-vat C c, as and forthe purpose herein described. i

'lhe above specification of our invention signed by us this 9th. .dayotApril, 1866.
